Abstract
Sum and difference frequency generators of Er3+:CaF2 ((lambda) equals 2.76 micrometers ), Er3+:YAG ((lambda) equals 2.94 micrometers ), and cw CO2 lasers with ZnGeP2 and CdSe single crystals has been developed to enlarge the possibilities of spectroscopic systems based on CO2 lasers. The generated spectra overlapped the ranges from 2.1 to 2.3 and from 3.7 to 4.3 micrometers which coincide with the two main atmosphere transparency windows. The energy effectiveness of sum frequency generation with 4.5 mm ZnGeP2 crystal realized is about 3% at phase-matching angle of 52 degree(s) and 12% for difference frequency generation in 40-mm CdSe crystals at phase-matching angle of 72 degree(s)40'. The latter source, in particular, may be used in CH4 lidar.
